The discharges per min. and the coefficients are plotted in
Fig. 1059, and shew a gradual decrease in the coefficient with
larger heads.

P. ?jo. The Hydraulic Impulse Ram.A special form
of this most important contrivance is illustrated in Fig. 1060,
where the power water and delivery waflr are obtained from
separate sources. In this manner, the former may be drawn from
